IMPROVEMENT IN GAS-GOVERNORS.

Specification forming part of Letters Patent No. l 86,299, dated January16, 1877; application filed December 1, 1876.

To all whom it may concern Be it known that I, JOSEPH R. BLOSSOM, ofBrooklyn, Kings county, State of New York, have invented Improvements inGas-Governors, of which the following is a specification My inventionconsists of a gas -regulator constructed, as fully described hereafter,to regulate automatically the supply of gas; to prevent waste resultingfrom undue increase of pressure at the burners, insuring more thoroughcombustion,-and consequent greater illumination; to prevent theaccumulation of moisture in the casing, facilitate the adjust ment andinsure uniform and certain action of the operative parts, and toincrease the durability of thediaphragm.

In the accompanying drawing, Figure 1 is a sectional elevation of myimproved regulator; Fig. 2, a sectional plan on the line 1 2, Fig. 1;and Figs. 3, 4, 5, detached sectional views, showing modifications.

The casing A of the regulator or governor is of any suitable form ordimensions, and is divided by a horizontal partition, to, into twochambers, X X, which communicate through a central opening. at,surrounded by a slight flange, b, and formed at the edge into a seat forthe hollow valve B. The upper portionof the valve-stem O is tubular, andextends through two flexible horizontal diaphragms,

"D D, clamped tightly between two nuts, 0, on

the stem, the portion of the stem below the valve being guided inacross-piece, d. The edges of the two diaphragms are clamped between anannular shoulder, e, at the inside of the case, and a ring, (3 having anupright flange, 6 the ring being less in diameter than the case, leavingan annular receptacle, t, for oil, which, having access to the edge ofthe diaphragm, is absorbed by the latter, and

, maintains it in a soft flexible condition, im-

parting a durability which it could not possess if permitted to becomedry and hard.

The diaphragms may be of any suitable materials; but I prefer leatherfor the lower, and bladder for the upper, the latter conveying to andretaining the necessary amount of oil upon the lower, protecting it, andpreventing the contact of air, which tends to evaporate or harden theoil.

The inlet-pipe E extends through the bottom ofthe case, andcommunicates, through the partition, with the chamber X, while theoutlet-pipe F leads from the chamber X. A small siphon-tube, G, whichmay be filled with porous or fibrous substance t, has a minute orificeat the inner end, and extends through the pipe E, near the bottom of thechamber X, its end within the pipe being lower than that within thechamber. To an opening, 9 in the bottom of the case, is applied a valve,8, having a pin smaller than the opening extending through the latter,to permit the valve to be raised from the outside to test the presenceof and remove moisture from within the case; and in the detachable capit is a central opening, m, provided with a burner, if required, todetect the escape of any gas,-if leakage occurs in the diaphragm.

.A curved apron, I, suspended from the partition a, between the valveand the outlet, extends nearly to the bottom of the case. The pressureof gas upon the flexible diaphragm determines the position of the valvein respect to its seat, and regulates the extent of the opening at, andthe passage of gas through the same,'the apron I preventing such acurrent of gas toward the outlet as would cause undue pressure upon theopposite side of the valve.

Shot, introduced through the hollow stem 0, weights the valve below its.seat, and prevents thatoverbalancing which results from placing the mainweight above the diaphragms; but additional adjustment may be obtainedby small weights (in addition to the shot) applied to the end of thestem, but free from contact with the diaphragm, to prevent abrasion. Theflange 1) around the opening 00, or the elevation of the partition atthis point, causes moisture in upper chamberto flow to the inlet E,instead of upon the valve, and also prevents tarry matter from flowingto or accumulating upon the valve-seat.

Minute indentations y are made in the partition, preferably at the edgeof the opening at, to permit the passage of a small volume of gas shouldthe valve be suddenly closed, thus equalizing the pressure. Any moisturewhich accumulates in the lower portion of the casing will be conductedthrough the siphon G, or by the fibrous material 3 into the inlet E. As,

however, a small portion of gas might pass inward through the pipe, 1bend the same to form a U-trap, p, from which the water will flow, butthrough which the gas cannot pass. (See Fig. 3.)

Although I have shown a spring-valve, s, a valve of differentconstruction may be employed-for instance, a screw-plug having flatfaces or recesses n, Fig. 4, through which the water can pass when theplug is turned to bring the recesses above the bottom of the casing.

While it may be preferable to form a receptacle, t, between the flange eand the casing, it may be formed by means of two flanged rings, as shownin Fig. 5; and instead of bring ing the oil into direct contact with theedge of the diaphragm, it may be conducted from the receptacle by a wickor fibrous material, w.

I am aware that a hollow valve and tubular stem have been combined witha float, and make no broad claim to these features; but

I claim- 1. The combination, with the flexible horizontal diaphragm, ofa tubular stem and a hollow valve, guided by a cross-piece, f, below thevalve, whereby the load may be intro duced into the guided valy e fromabove the diaphragm, as set forth.

2. The chamber X, communicating with the inlet E, and having an outlet,:10, above the valve, flanged or elevated above the bottom of thechamber, as set forth.

3. The combination of the valve, valve-stem, and two flexiblediaphragms, clamped together at the edges, and to the stem which passesthrough both diaphragms at the center, as and for the purpose set forth.

4. The combination of the valve, valve-stem,

and two non-metallic flexible diaphragms of different materials, clampedtogether at the edges and to the stem, as and for the purpose set forth.

5. The combination of the flange or ring a,

horizontal diaphragms, and flanged clampingring 0 forming an annularoil-receptacle at the edge of the diaphragm clamped between the two, asset forth.

6. A regulator provided with a continuous open passage, arranged topermit the continuous escape of drip from the bottom of the casing tothe inlet-pipe, as described.

7. The U-shaped pipep, communicating with the bottom of the chamber andwith the inletpipe, and forming a trap, as specified.

8. The valves, arranged at the bottom of the regulator, and closing anoutlet communicating with the atmosphere, for the purpose set forth.

9. The apron I, arranged between the valve and outlet, for the purposespecified.

In testimony whereof I have signed my name to this specification in thepresenceof two subscribing witnesses.
